PSU makes buzzing sounds while gaming.

[Medic Spy]

While Im playing games I can hear buzzing sounds coming from my PSU. Different games make different buzzing sounds and sometimes changes tune when Im looking around in game. Its a 750W PSU and is about 1 year old now. Is there any solution to this problem without having to buy a new one, if not what would you recommend.
Specs
CPU: AMD FX 4100 quad
RAM: 8MB
GPU: 7970 black edition
PSU: Antec 750W

Are you sure it is the PSU? my guess is that is is your GPU which is blowing at variable speeds depending on how much power the game/area is demanding.

I thought that at first and I got it replaced today actually only to find the problem has not gone away. Is it possible that my PSU has just gone bad and is struggling to keep up now?

 

[ryan27968]

Probably your fan has gone bad on your PSU then. Could also be your CPU fan.

I put the GPU's fan speed to 100% in CCC and it all sounds normal. So yeah could be the PSU fans.

 

[ryan27968]

Try setting the CPU fan to full as well and see if it makes that noise.

 

[Medic Spy]

Just done that and the CPU fans sound just fine. It just has to be the PSU.

 

[ryan27968]

Try playing your game again and wait for the strange sound to return, then, very carefully take a pencil or something like that and try to stop the fan with it (not for more than a few seconds) and see if it stops. If so, you just need to replace the fan.

It's probably the coil vibrating while under load.

Possibly. Just replace your psu if it bothers you that much.

Yep replaced the PSU and upgraded to a 850W just because I can. Sound is gone and probably not going to get another Antec anytime soon.

Which brand did you buy? Antec PSUs are usually very reliable.

I went for an XFX brand this time. lets see how this turns out 😛

I have a similar situation. Is this dangerous, should I get a replacement?

For me, while I was playing games after a minute or so I would get a black screen and hear looped sounds and I'd have to restart. I guess it turned bad and couldn't handle heavy loads anymore so I replaced it.

Your situation could be coil whine or a sign that its turning bad. Is it an old PSU?
